n 1945, two high-ranking members of the Nazi-sponsored Ustaše regime in the puppet Independent State of Croatia manage to escape the country with vast amounts of Croatian Holocaust-era loot, just before Allied troops move into Zagreb and Belgrade with the help of Partisan troops. Croatia ceases to exist as an independent state, and a new Yugoslavia is created by the Partisans. The two former Croatian officials are nowhere to be found.
Sixty years later, in 2005, elite multinational counter-terrorism unit Rainbow finds itself investigating a series of attacks by neo-fascist terrorists against South American oil interests and European financial institutions. The squadron is enlisted to ascertain their location and find out who is ultimately behind these incidents.
